    Overview

    This analog signal isolator supports loop powered or external 24V supply. In loop mode, it acts as a loop powered isolator; external power enables passive isolator 4‑20mA. Accepts 4‑20mA, 0‑20mA, 0‑5V, 0‑10V inputs/outputs. Options: 1‑in‑1‑out, 1‑in‑2‑out, 2‑in‑2‑out. Accuracy 0.1% FS, drift ≤0.2%/yr. Load: current 350Ω, voltage ≥10kΩ. Features 1500VAC isolation, pluggable PCB, DIN rail (96×18×122mm). Ideal for PLC/DCS.

    Feature

    • Power source: selectable loop or external power, functioning as a passive 4-20mA isolator to eliminate extra supplies and simplify wiring.
    • Accuracy & stability: 0.1% FS accuracy and ≤0.2%/year stability ensure drift-free transmission, critical for precise process control.
    • Modular design: pluggable PCB power board with separable isolating module permits exchange without rewiring, simplifying maintenance.
    • Signal compatibility: wide compatibility (4-20/0-20 mA and 0-5/0-10 V) lets one isolator cover multiple types, reducing spare parts.

    FAQ
    ❯

    A: Loop-powered mode: the input signal (4-20mA) powers the isolator – no extra wiring. Externally powered mode: requires a separate DC 24V supply. Switch via onboard DIP switch: up for loop-powered, down for externally powered. Adapts to different field wiring conditions.

    ❯

    A: Signal types: 4-20mA, 0-20mA, 0-5V, 0-10V. Three channel configs: 1-in-1-out, 1-in-2-out, 2-in-2-out. Choose as needed.

    ❯

    A: Current output load capacity: 0–350Ω. Voltage output load requirement: ≥10kΩ. Compatible with most PLC analog input modules and indicators. For driving multiple devices or long-distance transmission, ensure total load does not exceed 350Ω.
